QB/T 2678-2004

Footwear machinery manufacturers use this standard to design and produce box-type hot and humid shaping machines, ensuring equipment performance meets industry requirements. Shoe factories employ these machines to shape natural and synthetic leather uppers, eliminating internal stress and improving fit and final product quality. This standard unifies technical parameters and inspection rules, ensuring reliability and production efficiency.

制鞋机械制造商使用本标准来设计和生产箱式湿热定型机，确保设备性能符合行业要求。鞋厂利用该设备对天然革和合成革鞋面进行定型处理，消除内应力，提升鞋面贴合度和成品质量。本标准通过统一技术参数和检验规则，保障设备可靠性和生产效率。

This standard specifies product classification, technical requirements, test methods, inspection rules, and marking/packaging for box-type hot and humid shaping machines. It applies to equipment used in footwear production to eliminate internal stress and shape natural and synthetic leather uppers. Key technical parameters include working temperature 90-140°C, temperature difference in drying tunnel ≤5°C, and heating rate reaching 140°C in 10 minutes. Requirements cover assembly quality, machine performance (e.g., insulation resistance, voltage withstand, noise ≤80 dB(A)), and load tests. It references multiple GB and QB standards to ensure safety and reliability.
